Dissolve the chemicals separately and then mix. The glycin will slowly dissolve after mixing.
Filter the solution through a damp linen cloth.
Development time, undiluted, is between 20 to 25 minutes at 68F/20C.
NOTE 1: This formula results in at least a one stop loss in speed. By increasing the glycin to
as much as 12.0 grams, fi lm sensitivity can be increased, but the fi ne-grain effect decreases.
NOTE 2: Any gray coating remaining on the fi lm after development can be removed by a 3%
solution of glacial acetic acid.

Metol, 6.2 g
Sodium sulfi te, 90.0 g
p-Phenylenediamine, base, 10.4 g

Use undiluted. Develop slow speed fi lms for 11–16 minutes at 68F/20C.
FORMULA #62
FX 10 (1961)
(Geoffrey Crawley)
This formula is reputed to be the only true superfi ne-grain developer known not to cause a
loss of emulsion speed. It is very sensitive to overexposure and overdevelopment. This developer
may very well prove useful with tabular grain fi lms. Try diluting it 1:3.
Sodium sulfi te, 100.0 g
*Kodak CD-2, 7.5 g
Hydroquinone, 6.0 g
Borax, 4.0 g
Boric acid, crystalline, 4.0 g
Water to make 1.0 liter
* Kodak CD-2 is N,N-diethyl-2-methyl-p-phenylenediamine, monohydrochloride; this is a
p-phenylenediamine derivative used in color developers.
Develop fi lms for approximately 5 to 11 minutes at 68F/20C.
If the fi ne-grain effect is found to be too great and dichroic fog results, the sulfi te content
can be lowered. Alternatively, the amount of boric acid could be reduced, the borax increased,
or both. Development times would be shorter.
